Abstract Using the ARGUS detector at the storage ring DORIS II we have measured τ decays into three charged mesons containingK * mesons. Exploiting the good particle identification capabilities of the detector we have determined the following branching ratios: $$Br\left( {\tau ^ - \to \overline... mehr

Abstract The differential cross sections for Bhabha scattering and μ pair production, and the total τ pair cross section as measured by the PLUTO detector at PETRA, have been analyzed to extract information on the weak interaction of leptons. The data are compared with unified gauge theories.... mehr

Abstract The jet character of the hadronic final states produced ine + e − annihilations is studied in terms of jet measures such as thrust, sphericity, jet opening angle and jet masses, in the energy range 7.7 to 31.6 GeV. All distributions and averages have been corrected for detector effects... mehr

Abstract An analysis of the decay τ-→π-π0 v τ has been performed using the ARGUS detector at the DORIS II storage ring. The branching ratio has been determined to be Br(τ-→π-π0 v τ=(22.6±0.4±0.9)%. The shape of the π-π0 invariant mass spectrum is found to be in good agreement with... mehr
